HP7500 and Printing 12x12 with a Max

I am trying to figure out how to configure my printer to print 12x12 layouts/scrapbook pages.. I am operating Mac OSX 10.9.2 .. I do not have an option to choose scrapbook paper and or 12x12 when I originally purchased this printer I had the scrapbook option but I stopped using the printer and now do not have that option.
